Their most distinctive feature is a strong bony spike on their front limbs that looks like a thumb. Why that spike evolved is still a mystery though. Maybe they used it as a weapon against predators or other Iguanodons. Maybe it was used to break into seeds and fruit or as a hold while collecting food in trees.
